The display unit 2000 includes a sub-LED display screen 300 and a cabinet 400, and structurally speaking , The sub-LED display 300 is arranged on the upper part of the box 400.

The control system 1000 includes a sending module 100 and a receiving module 200. A receiving module 200 is provided in the cabinet 400 of the display unit 2000, and the receiving module 200 is electrically connected to the corresponding sub-LED display screen 300. The sending module 100 is in signal connection with the receiving module 200 in the box.

It is understandable that when the LED display screen is in normal use, it is generally composed of several display units. Among several display units, the sub-LED display screens of each display unit display part of the picture, and the sub-LED display screens of all display units combine to display the complete picture. Therefore, generally assembled LED display screens include multiple display units, and a receiving module is installed in the box of each display unit. Then, at this time, the sending module is connected to one of the receiving modules, and all the receiving modules are connected in series.

Generally, when using the above-mentioned LED display, you need to first install the cabinet on the ground or wall where the picture needs to be displayed, and then install a sub-LED display on each cabinet. When displaying a picture, each sub-LED display shows a part of the picture, and all the pictures displayed on the sub-LED display combine to form a complete picture.

After the LED display is installed, the sending module sends instructions to the receiving module. After receiving the instructions, the receiving module controls a part of the corresponding sub-LED display screen. When each sub-LED display screen correctly displays a part of the screen that should be displayed, the screen of the entire LED display screen can be displayed correctly.

Based on the above LED display screen, the embodiment of the present application provides two LED display screen connection methods.

ID information.

Specifically, after the LED display is spliced, the sub-LED display is controlled to display ID information, and then the entire LED display is photographed, and then the physical position of the sub-LED display in the photo is analyzed. After confirming the physical location, identify the ID information displayed on the screen of the sub-LED display that was taken. What needs to be clear is that the physical location of each display unit corresponds to the ID information one-to-one.

The ID information can be the serial number of the connection between the sending module and the receiving module in the box of the display unit when they are connected; or the unique factory number that comes with the box when it leaves the factory; it can also be a randomly generated character code, and then The barcode or two-dimensional code obtained after one-to-one mapping of the character encoding. The ID information can also be a number generated by using numbers or words, or a barcode or two-dimensional code generated from the number; or other identification codes generated by image processing of a barcode or two-dimensional code.

What needs to be clear is that as long as the ID information of each cabinet is different, the specific form of the ID information can be set according to actual needs, as long as it can be used to distinguish each cabinet.

The control sub-LED display screen displays the connection serial number, factory number, bar code or two-dimensional code, which can be preset in the receiving module to display what kind of information. As long as the assembly of each display unit is completed, after power-on, the sub-display will display the preset ID information. If the ID information is a connection serial number, the receiving module can automatically identify the connection serial number during the assembling process without manual confirmation.
